A UV index reading of 6 to 7 indicates a high risk of harm from unprotected sun exposure.
Since Hanoi's UV index is expected to reach 7 today, it's crucial to take extra precautions to protect your skin from the harmful effects of UV rays.
To reduce your risk of skin and eye damage, it's best to limit your time in the sun between 10 a.m. and 4 p.m.
If you need to be outdoors during this time, seek shade and wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
Be sure to generously apply broad-spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days and after swimming or sweating.
Keep in mind that bright surfaces like sand, water, and snow can increase UV exposure, so take extra care in these environments.
